Using This Guide

The Diskless Workstation Administration Guide explains how to configure and maintain Silicon Graphics® software so that one or more networked workstations can operate without a local disk. It introduces the terms and concepts needed to understand a diskless implementation and explains how to plan an implementation. It also describes the procedures needed to install, maintain, and troubleshoot a diskless implementation.

Product Requirements

Silicon Graphics' implementation of Diskless Workstation software should be used with these requirements in mind:

  • Diskless Workstation software must be used in conjunction with Silicon Graphics' Network File System (NFS™) software option.

  • To implement 5.1 or later versions of IRIX on diskless clients, the diskless server must be running IRIX Release 5.1 or later.

  • The Diskless tools that install IRIX 5.1 software cannot be used to install earlier versions of IRIX. See the Release Notes that accompanied this product for instructions on installing pre-IRIX 5.1 software.

  • The server and client systems must be on the same physical and logical network: the diskless client-server relationship cannot be implemented by means of a router.

Summary of Contents

The Diskless Workstation Administration Guide is organized into seven chapters and an appendix:

Chapter 1, “Understanding Diskless Operation” 


Introduces the elements of a diskless network and explains the organization of diskless software on the server. Read Chapter 1 to understand how diskless implementations work.

Chapter 2, “Preparing for Installation” 


Explains how to get the hosts in a LAN ready for a diskless implementation and describes how to organize diskless software directories. Use Chapter 2 as a guide to setting up a diskless implementation for the first time.

Chapter 3, “Creating a Share Tree”  


Explains how to configure and install the software that is shared by diskless clients. Use Chapter 3 when installing a new share tree. Do not use Chapter 3 to update an existing tree with a new software release.

Chapter 4, “Creating Client Trees” 


Explains how to configure and install the software that is used by an individual diskless client. Use Chapter 4 when installing a new client and swap tree. Do not use Chapter 4 to update an existing tree with a new software release.

Chapter 5, “Updating Software on Diskless Trees”  


Explains how to upgrade a diskless software installation to a new software release and how to add software options to a diskless implementation.

Chapter 6, “Maintaining Diskless Implementations” 


Contains instructions for performing routine server maintenance. Use the information in Chapter 6 to move a diskless server or software to a new location, remove a server or diskless software from service, or reconfigure the client with local resources.

Chapter 7, “Troubleshooting Diskless Installations” 


Describes problem-solving techniques for diskless setups and suggests how to get the best results from service calls to Silicon Graphics' Technical Assistance Center.

Appendix A, “Determining the Client Architecture” 


Provides supplementary information for specifying workstation hardware in the client configuration file. Refer to Appendix A if the hardware information for a client workstation is not listed in either Chapter 2 or Chapter 4 of this guide, or in the distribution copy of the client.dat file.

The Audience for This Guide

The Diskless Workstation Administration Guide is written for system and network administrators who will be responsible for managing a Silicon Graphics server that supports one or more diskless workstation clients. It assumes that the audience has experience with basic system administration on an IRIX™ or other UNIX-based system.

Experience in maintaining IRIX filesystems and NFS, and in installing Silicon Graphics software are helpful, but not required, to install and maintain Diskless Workstation software. A familiarity with various families of Silicon Graphics workstations is also helpful, particularly for doing troubleshooting procedures. At some sites, familiarity with network administration will be required to prepare network software for the diskless implementation.

Notation Conventions

This document uses the standard UNIX® convention when referring to entries in IRIX documentation. The entry name is followed by a section number in parentheses. For example, cc(1) refers to the cc manual entry in Section 1 of the IRIX User's Reference Manual, Volume 1.

In-text descriptions, file and directory names, as well as commands, are shown in italics; and options appear in bold. Command syntax descriptions appear in typewriter font, with variable names in italics. User entries are shown in typewriter bold.
